“Today’s Poll of Polls average reflects the fact that Obama has moved into a commanding position in the presidential race,” said CNN Senior Political Researcher Alan Silverleib. “Obama is either tied or ahead in all of the battleground states. The Democrats now have what may be a decisive edge in terms of voter enthusiasm and financial resources. The financial meltdown has played to Obama’s advantage. By most measurements, McCain was not able to use the debates to gain ground on Obama. And most of the campaign is now being waged in previously red states. While anything can happen in the remaining two weeks, it’s hard not to conclude that McCain’s back is against the wall.”

Tuesday’s CNN poll of polls is composed of the following six national general election surveys of likely voters: Pew (October 16-19), CNN/ORC (October 17-19), ABC/Washington Post (October 16-19), Reuters/C-SPAN/Zogby (October 18-20), Gallup (October 18-20) and Diageo/Hotline (October 18-20).

Sen. McCain is trailing in Minnesota despite the fact that the Republican convention was held in St. Paul.

(CNN) – With less than a month to go until Election Day, CNN’s latest Minnesota poll of polls shows a major advantage for Sen. Barack Obama.

Obama now leads Sen. John McCain by 14 percentage points – with support from 54 percent of likely voters in the state, compared to 40 percent for McCain. Six percent of likely Minnesota voters are unsure about their choice for president. In CNN’s previous Minnesota poll of polls, Obama was ahead of McCain by a single point – 47 percent to 46 percent.

“The meltdown on Wall Street has significantly strengthened Obama’s hand in Minnesota,” noted CNN Senior Political Researcher Alan Silverleib. “The crisis has reinforced the state’s traditional embrace of economic populism, which almost always benefits the Democrats. At the same time, any local bounce McCain might have received from holding his party’s convention in St. Paul has now worn off. It’s worth remembering that no Republican candidate has carried Minnesota since Richard Nixon in 1972; it’s tough to imagine any GOP candidate seriously contesting the state when he’s trailing nationally by five or six points.”

Tuesday’s CNN Minnesota poll of polls is made up of the following three surveys: Minnesota Public Radio/Humphrey Institute (October 3-5), Star Tribune (September 30-October 2) and CNN/Time/ORC (September 28-30).

The poll of polls does not have a sampling error.

(CNN) – Less than a month before Election Day, Barack Obama appears to hold a growing advantage over John McCain in the traditionally red state of Virginia, according to a new CNN Virginia poll of polls released Monday.

Obama has the support of 49 percent of likely voters in the state while McCain has the support of 45 percent. Six percent remain unsure about their choice for president.

In CNN’s previous Virginia poll of polls, released on October 2, Obama was ahead of McCain by a single point – 48 percent to 47 percent.

“Virginia hasn’t voted for a Democratic presidential nominee in 44 years,” noted CNN Senior Political Researcher Alan Silverleib. “But the combination of a struggling economy and the state’s changing demographics might be enough to turn the tide this time. If Obama wins the D.C. suburbs in Northern Virginia by a landslide while benefiting from a large turnout from African-Americans and younger voters statewide, the Democrats might carry Virginia’s 13 electoral votes. That would be a serious blow to McCain.”

Monday’s CNN Virginia poll of polls is comprised of the following four surveys: Suffolk (October 3-5), CNN/Time/ORC (September 28-30), Mason-Dixon (September 29-October 1), and ARG (September 27-29). The poll of polls does not have a sampling error.
